The idea of using inflatables for space habitation has been around for a long time, but was seriously revived by NASA in the late eighties. A group at Johnson Space Center designed inflatable lunar habitation back then, including building test articles. And there is currently an experimental inflatable module on the International Space Station. http://www.nss.org/settlement/moon/library/LB2-303-InflatableHabitation.pdf http://www.nss.org/settlement/moon/library/LB2-303-Inflatabl... https://er.jsc.nasa.gov/seh/gotomoon.html https://er.jsc.nasa.gov/seh/gotomoon.html
